I only have a moment to write, but I want to suggest checking out a blog post by Gary Schwitzer, former head of CNN's medical news division and current professor at the University of Minnesota's School of Journalism and Mass Communications. Mr. Schwitzer raises concerns about Dr. Sanjay Gupta's possible appointment to be Surgeon General, and offers rather informative criticism of the TV doctor's work from a journalist's point of view. The post can be found here [1]. (Scroll down to January 12 to read find the post.)
